Ok man so here's how it is for ME anyways...
Yes you can become dependant but not on the same level as someone who shoots dope daily or anything. I do the same thing but I CWE... its very important to do that... well today I didn't but the first dose of a binge I don't.
I myself do not have a tolerance (I guess I do but I take 2 weeks off, and then binge for 3 days or so with it - 50 pills every 12-14 days)... which is crazy because I take 90mg hydrocodone (10/ 325 norco) and it gives me energy but yet sedation at the same time.... it makes me productive more or less....
Anyways when I run out after 24/7 abuse of high amounts of hydro I don't feel much for "withdrawals/dependency". After about 36 hours in or so I sometimes get stomach cramps and diarrhea, but not bad... that lasts a day or so. I feel pretty down as well and depressed for the first 24 hours or so after stopping my use.
I usually average 150-170mg hydrocodone in one day. Three days or so on.... 10-14 days off... I don't use other opiates at the moment either...
So all in all, yes it is possible to get dependant but at that amount for that amount of time, it should not be bad at all.
But dude, cold water extract your hydro from now on.... I know I just took 9 norco and I'm sayin that, but like I said my first dose is the only dose I don't CWE... I don't know how unsafe that is but I CWE everything following the first dose so my liver doesn't have to suffer too much as the max is 4 grams.
90mg. the idea of that amount makes me laugh it sounds rediculous but theres people out there who take more MUCH more I imagine.
To the OP you should be ok, just CWE from now on.
*EDIT
When I said I do not have a tolerance I know I may sound like a retard by saying that, but I honestly think my tolerance is natural... ever since I did H two years back and then not doing any opiate for months, I dosed up on the hydro at 90mg and honestly it feels the same as it always did... it sucks I have to take so much though. I think my expectations have changed since messing around with stronger opiates or something but ever since Dope my experiences have never been the same with the weaker pain medicines as they use to be. I don't use every day either. H and shit, its been 2 years....
